Puzzle: Why does a for loop using the increment statement "x =+ 2" run forever?

Question

Suppose you want to iterate through the even natural numbers from 2 to 10. You could use the following code:

public class Program {
public static void main(String[] args) {
for(int x = 0; x <= 10; x += 2) {
System.out.println(x);
}
}
}
/*
Output:
0
2
4
6
8
10
*/
However, when you change the increment statement to x=+2 the loop never ends.
Why?

Answer 1

because =+2 is not the correct syntax for increment, so x value is not incremented. So the loop is infinite!

Answer 2

x=+2 actually sets x to 2 (rather the intended increment of x)

Answer 3

Thanks a lot!
